Overview of IEC 61508 - Design of electrical / electronic / programmable electronic safety - related systems
نویسنده
چکیده
The aim of the international standard IEC 61508 is to provide a route whereby safety-related systems can be implemented using electrical or electronic or programmable electronic technology in such a way that an acceptable level of functional safety is achieved. The strategy of the standard is first to derive the safety requirements of the safety-related system from a hazard & risk analysis and then to design the safety-related system to meet those safety requirements taking into account all possible causes of failure including random hardware faults, systematic faults in both hardware and software and human factors.

An Overview of IEC 61508 on E/E/PE Functional Safety
The International Electrotechnical Commission is the organisation which develops and sets international standards in electrotechnical engineering areas. In 1997 the IEC published the standard IEC 61508, Functional safety of electrical/electronic/programmable electronic safety-related systems. The phrase “electrical/electronic/programmable electronic” is cumbersome and is often shortened to E/E/...

It is estimated that about 66% of the Programmable Electronic Systems (PES) running in the process industry were installed before the publication of today’s commonly used safety standards (IEC 61508 and IEC 61511/ISA 84) Some of those safety systems, particularly the ones installed between the late 1980's and early 2000, are either 1. General-purpose PLCs, 2. Not designed or certified according...

متن کاملIntroduction to EMC for Functional Safety
Most safety regulations and standards concentrate their efforts on intrinsic safety – the possibility that injury or damage could occur due to electric shock, fire, mechanical instability, sharp edges, etc. In this paper we are concerned with functional safety – where the hazards and risks depend upon the correct operation of devices, equipment, systems or installations. IEC 61508 [3] is the ba...
